I understand that QEMU-virt is not intended to model a realistic
production platform and that QEMU-SBSA is generally preferred. However,
I sometimes use QEMU-virt to test functionality quickly because it runs
slightly faster than QEMU-SBSA.

I tested this series with QEMU-virt and found that RMM initialization
failed during boot:

   [...]
   INFO:    BL31: Initializing RMM
   INFO:    RMM init start.
   ERROR:   RMM init failed: -8
   WARNING: BL31: RMM initialization failed

I also ran into same issue and attached TF-A patch leads to a successful
RMM initialization, please have a try to see if it can resolve your issue.


Thanks,
Gavin
